Patented May 4, 1937 UNITED STATES REVOLVING SIGN Theodore P. Eichelsdoerfer, Rock Island, Ill.
I Application August 26, 1935, Serial No. 37,951 Renewed October 14, 1936 1 Claim.
My invention has reference to a revolving sign, and is more specially designed for use with display cards and banners of the smaller type, which .are usually supported from the face of a building, or from the hood of an automobile, and which are subjected to the force of currents of air which are rushing past. These signs are frequently made of card-board and other light material, and are liable to be bent one way or the other by the breezes until they break loose from their supports.
One of the purposes of the present invention is to provide a means whereby the card can swing freely, or rotate if necessary, about its support, so that there is no tendency of that part of the sign near the support being cracked or broken loose.
Another feature thereof consists in the provision of a support formed of a single piece of wire or rod, with a pair of end pieces capable of being quickly engaged or disengaged with a fixture of some sort. 7
Another purpose thereof is to provide a' simple and durable device, at a low cost of production.
The particular construction and arrangement of the parts of the invention will be more fully understood from the following specification, taken -"in connection with the accompianying drawing, in which;
Fig. 1 shows the invention in front elevation, as it appears when in use.
Fig. 2 shows the supporting frame, detached.
Fig. 3 is a cross-section on the broken line 3-3 of Fig. 1.
The reference number 5 indicates a fixture, to which is attached the supporting frame for a sign.
As set forth herein said frame consists of a body portion 6, formed of two strands of wire, spirally twisted and united at one end by a loop 1, and
The twists of the body portion form a shaft upon which is pivoted the tubular portion l3 of a double plate [4, between which is held a card or plate I5, the edges of which have metal bindings Hi, to prevent wear thereof. Said card is de- 5 signed for display or advertising matter on its opposite faces, and is adapted to swing freely on its support, so as to attract attention. If the force of a breeze is suificiently strong it will cause the sign to form complete revolutions on the 10 frame, with the sign held radially therefrom at all times. The sign is prevented from leaving the support by the loop I, and its movement in the opposite direction is limited by the spread of the bars 8 and 9.
The parts of the invention can be cheaply produced, the plate l4 being formed of a single piece of metal, and the support from a single piece of wire. When it is not desired to have the same in usethe invention can be quickly removed by slipping the prongs from their seat. While the invention has been shown herein with the support 6 in a horizontal position, it will be evident. that the same can be held in a vertical position, or in any position between a vertical and horizontal.
The invention is not only of advantage for use with small signs and display cards, but it can also be used with pennant, banners, .and small flags, including flags carried on automobiles by undertakers.
What I claim, and desire to secure by Letters Patent, is: r
A device of the class described, comprising a support formed of a single piece of wire twisted to provide a body portion having an enlarged loop at one end and divergent arms at the other end bent angularly to form prongs for insertion in a keeper at spaced points, a supporting plate having a tubular portion for pivotal engagement with said body portion, limited in its movement thereon in one direction by said loop and in the other direction by said divergent arms, and a display member attached to said plate.
